Energy saving method

ABSTRACT

A cooling and heating energy saving system includes a cooling and heating device, a data center, a boiler, a heat exchanger, and a circulating pump. The boiler receives excess heat of the data center and heat generated by the cooling and heating device, and then generates high-temperature heat and transfers the high-temperature heat to an indoor heating device. The heat exchanger receives heat from the cooling and heating device and the data center. The circulating pump receives the heat generated by the data center and transmits the heat to an outdoor cold source, and further transmits the outdoor cold source to an indoor device through the heat exchanger.

FIELD

The subject matter herein generally relates to cooling and heatingsystems, and more particularly to a cooling and heating energy savingsystem and an energy saving method using the cooling and heating energysaving system.

BACKGROUND

With the rapid development of communication technology, Internet datacenters have developed on a large scale. According to statistics, airconditioning in the computer room accounts for more than 50% of totalpower consumption in the computer room. Even if the outdoor temperatureis low in winter, the computer room still needs to be cooled. Thenatural cold air outside the computer room is a huge natural coldsource, which if designed wisely, can save energy for cooling thecomputer room. Furthermore, the low-temperature waste heat generated bythe data center has serious impacts and harms on the environment.Reusing the waste heat of the data center can not only reduce theenvironmental impact, but also reduces the consumption of other energysources and improves energy efficiency.

The cooling and heating device 10 performsindoor cooling or heating and is coupled to the outdoor heat source 11to obtain outdoor heat to supplement heating performed by the coolingand heating energy saving system 100. In one embodiment, when theambient temperature of the cooling and heating device 10 is lower than afirst preset temperature, the cooling and heating device 10 performsheating, and when the ambient temperature of the cooling and heatingdevice 10 is higher than a second preset temperature, the cooling andheating device 10 performs cooling. The first preset temperature may be10 degrees Celsius, and the second preset temperature may be 25 degreesCelsius. In other embodiments, the first preset temperature may be aboveor below 10 degrees Celsius, and the second preset temperature may beabove or below 25 degrees Celsius, as long as the first presettemperature is lower than the second preset temperature. The outdoorheat source 11 supplements the heat provided by the cooling and heatingenergy saving system 100. The data center 13 generates heat when thedata center 13 is started to work. The boiler 14 is coupled to thecooling and heating device 10 and the data center 13. The boiler 14receives waste heat generated by the data center 13 and heat from thecooling and heating device 10 to generate high-temperature heat, andthen transfers the high-temperature heat to an indoor heating device 18.

The heat exchanger 15 is coupled to the cooling and heating device 10and the data center 13. The heat exchanger 15 receives heat generatedfrom the cooling and heating device 10 and the data center 13. Thecirculating pump 16 is coupled to the data center 13, the outdoor coldsource 12, and the heat exchanger 15. The circulating pump 16 receivesthe heat generated by the data center 13 and transfers the heat to theoutdoor cold source 12 to dissipate the heat. The circulating pump 16also obtains a cold source from the outdoor cold source 12 and transmitsthe cold source to the heat exchanger 15, and then the heat exchanger 15transmits the cold source to an indoor device 19.

In one embodiment, the cooling and heating device 10 includes a heatingcomponent 10A and a cooling component 10B. The heat generated by theheating component 10A performs indoor heating, and the heating component10A is coupled to the boiler 14 and the heat exchanger 15 so that theboiler 14 and the heat exchanger 15 also receive the heat generated bythe heating component 10A. The cooling component 10B is coupled to anindoor cooling device 17, and the indoor cooling device 17 receives coldgenerated by the cooling component 10B for indoor cooling.

In one embodiment, the heat exchanger 15 is also used to transfer heatfrom the heating component 10A and the data center 13 to the indoordevice 19.

In one embodiment, the indoor cooling device 17 is a blower or anair-conditioner, but not limited thereto.

In one embodiment, the heating component 10A is a heat pump, and thecooling component 10B is a chiller, such as a water-cooled chiller.

The boiler 14 is coupled to the indoor heating device 18, the datacenter 13, and the cooling and heating device 10. The boiler 14 is usedto receive the heat transferred from the heating component 10A of thecooling and heating device 10 and recover the waste heat generated bythe data center 13, and then produce high-temperature heat and transmitthe high-temperature heat to the indoor heating device 18. The indoorheating device 18 heats an indoor room after being heated.

In one embodiment, the indoor heating device 18 can be a reheater or afloor, but is not limited thereto. The reheater may be an airconditioning reheater or a blower reheater. The reheater is used toreceive the heat of the boiler 14 and transfer the heat to a cold airoutlet of the reheater so as to avoid the problem of condensation tomaintain a comfortable indoor temperature environment.

In addition to consuming energy sources such as electric power, gasenergy, or kerosene for heating, the boiler 14 receives heat from theheating component 10A of the cooling and heating device 10 and recoversthe waste heat of the data center 13, so as to reduce the energyrequired in the heating process of the boiler 14, which is moreenvironmentally friendly.

The heat exchanger 15 is coupled to the data center 13, the circulatingpump 16, and the indoor device 19. The circulating pump 16 is coupled tothe outdoor cold source 12. The waste heat generated during theoperation of the data center 13 is not only recycled through the boiler14 and the heat exchanger 15, but also causes the temperature of thedata center 13 to increase. The excess waste heat of the data center 13is transferred to the outdoor cold source 12 through the circulatingpump 16, and the outdoor cold source 12 is used for auxiliary heatdissipation.

In one embodiment, the circulating pump 16 is also used to transfer theoutdoor cold source 12 to the heat exchanger 15, and the heat exchanger15 transmits the outdoor cold source 12 to the indoor device 19. Theoutdoor cold source 12 is used to perform indoor cooling to reduce thepower consumption of the cooling and heating device 10 during thecooling process, thereby achieving an energy saving effect.

In one embodiment, the indoor device 19 is a chilling beam or blower,but is not limited thereto.

In one embodiment, the boiler 14 is a heat recovery hot water boiler.

In one embodiment, the heat exchanger 15 is a plate heat exchanger.

Transmitting the waste heat generated by the data center 13 to theoutdoor cold source 12 through the circulating pump 16, and dissipatingthe waste heat by the outdoor cold source 12.

The cooling and heating energy saving system 100 uses the cooling andheating device 10 and the boiler 14 to perform indoor cooling andheating requirements. At the same time, the waste heat generated duringthe operation of the data center 13 is recycled and reused. The outdoorheat source 11 is used to supplement the indoor heat and the outdoorcold source 12 is used for heat dissipation and cooling.
